It was able to handle the function of cooling.

The present applicant has been researching to develop the technology related to the fixed hopper loader, and as a result, it was filed as Utility Model Registration Application No. 24467 (Date of January 1, 1998) in 2000 and published Utility Model Application Publication No. 11175 in 2000. There is a fact that the application of the "cyclone separation device of the fixed hopper roder" published in the application.

The cyclone separation device of the fixed hopper rod is "cover cover which is assembled to communicate internally under the raw material suction device of the hopper rod, and is inflowed through the raw material introduction pipe which is detachably attached to the cover cover and connected to a predetermined position. In the raw material inlet can be secured to accommodate the raw material to be stored, and the separation means which is disposed inside the cover cover and the raw material inlet to separate the raw material introduced into the raw material inlet and intake air And, the filtering means has a mesh with a fine mesh is formed, so that the reinforcing net formed with a relatively large mesh is disposed on the upper surface of the mesh, and the outer edge of the strainer and the reinforcing net is fixed with a flexible flow ring member, the By placing a vibrator in the center of the upper part of the reinforcing net to vibrate the strainer up and down. Jiro was.

According to the cyclone separator of the fixed hopper loader, not only the fine particles are separated and filtered by the suction air together with the synthetic resin raw material as the filtering net, but the fine particles filtered by the filtering net are shaken off by the vibration of the vibrator to remove the synthetic raw material. It has the advantage of being able to supply by inhaling smoothly.

However, the cyclone separation device of such a fixed hopper rodder has a serious result that the viscous microparticles stick to the strainer and lose the function of sucking the synthetic resin raw material.

In more detail, when the fixed hopper rod is operated to supply a pigment with viscous particles as fine particles to the injection molding machine together with the synthetic resin raw material, the cyclone separator of the fixed hopper rod is a synthetic resin raw material sucked as a strainer. And the pigment is separated and filtered by suction air. At this time, the pigment with viscous as fine particles sticks to the strainer and is not easily removed by vibration of the vibrator. As the blinds are clogged, they are not able to supply synthetic resin raw materials and pigments smoothly during the operation, and thus the work efficiency is greatly reduced, and they have to deal with the inconvenience and inconvenience of having to clean or replace the strainer from time to time. It was accompanied.

It is an object of the present invention to provide a cyclone separation apparatus of a fixed hopper loader having excellent filtration ability to reliably collect and filter fine particles contained in intake air without regard to kind.

Still another object of the present invention is to provide a cyclone separation device of a fixed hopper rod that allows the supply of a synthetic resin raw material without suction loss by viscous fine particles.
